We have a hint from Stefan saying that many users are facing battery life decreasing since upgrading to iOS 4.3. It seems that Ping is draining battery life of iPads faster than before upgrading to iOS 4.3. It will probably be fixed on the next versions of operating software, but until then, a simple solution is to turn off Ping.
4 easy steps bellow:
1. Press the Settings Icon.
2. Choose General.
3. Go to Restrictions and enable them. You’ll be asked for a 4 digits passcode. Remember it or write it down because you will need it every time you go into Restrictions Menu.
4. Set Ping Off.
You will now restore your battery life to normal.
Thank you Stefan for the tip.
